Ответ:
It must be less than 4 but greater than -4
Step-by-step explanation:
1 - Give our unknown a variable
We'll give the integer the value x
2 - Write out the equation
| x | < 4
Because absolute value means its always positive, this means it has a range between -4 and 4 when given the rule that it must be less than and not equal to 4.
So his number x must be less than 4 but greater than -4
This is written as -4 < x < 4
